En mi build.gradle :

 "com.squareup.okhttp3:okhttp:3.13.1", 'com.squareup.okhttp3:logging-interceptor:3.13.1',

Proyecto Kotlin abierto conectar a websocket:

 const val WEB_SOCKET_URL = "wss://api.lbkex.com/ws/V2/"; fun main(args: Array<String>) { val оkHttpClient = OkHttpClient() val wsListener = object : WebSocketListener() { override fun onOpen(ws: WebSocket, response: Response) { super.onOpen(ws, response) val requestJson = """{"action": "subscribe", "subscribe": "tick", "pair": "vtho_eth"}""" ws.send(requestJson) } override fun onClosing(webSocket: WebSocket, code: Int, reason: String) { super.onClosing(webSocket, code, reason) logger.info("ws Closing, reason = " + reason) } override fun onClosed(webSocket: WebSocket, code: Int, reason: String) { super.onClosed(webSocket, code, reason) logger.info("ws Closed") } override fun onFailure(webSocket: WebSocket, t: Throwable, response: Response?) { super.onFailure(webSocket, t, response) logger.error("ws Failure ", t) } override fun onMessage(webSocket: WebSocket, text: String) { super.onMessage(webSocket, text) logger.info("ws Text message: $text") } override fun onMessage(webSocket: WebSocket, bytes: ByteString) { super.onMessage(webSocket, bytes) } } logger.info("Started") val wsRequest = Request.Builder() .url(WEB_SOCKET_URL) .build() val ws = оkHttpClient.newWebSocket(wsRequest, wsListener) }

Como resultado, abrí con éxito webscocket en wss://api.lbkex.com/ws/V2/ .

Como resultado, el método onMessage se llama muchas veces. Lindo.

Pero después de 15 minutos, llame al método onFailure con error:
